Secondary Antibodies

CF® Dye-Labeled Secondary Antibodies

Choose from a wide selection of highly specific and versatile fluorescent secondary antibodies conjugated to your choice of 20+ bright and photostable CF® Dyes.

CF® Dye Single Label Conjugates for STORM

Elevate your super-resolution imaging with fluorescent conjugated antibodies developed and optimized for STORM, with an average degree of labeling (DOL) of one.

Anti-Epitope Tag & Anti-Biotin Antibodies

Detect, purify, and visualize epitope tags like biotin, GFP, and FITC with precision across multiple assays, including Western blot and immunohistochemistry (IHC).

Anti-Human Immunoglobulin

Target human IgG, IgA, IgM, and more with highly specific secondary antibodies—available purified or with a wide range of labels to support diverse immunoassays.

Biotinylated Secondary Antibodies

Amplify signals of low-abundance proteins with biotinylated secondary antibodies, ideal for Western blot, immunofluorescence, and IHC in FFPE tissues.

Alkaline Phosphatase Conjugates

Achieve strong, long-lasting enzymatic signal detection with alkaline phosphatase (ALP)-conjugated secondary antibodies for ELISA, IHC, Western blot, and more.

Horseradish Peroxidase (HRP) Conjugates

Power chemiluminescent and colorimetric detection with HRP-conjugated secondary antibodies, delivering reliable signals for immunoassays and enabling tyramide signal amplification.

R-PE & APC Labeled Antibodies

Enable bright, multi-color detection in flow cytometry and beyond with fluorescent conjugated antibodies, offering high sensitivity and minimal spillover.

Biotin & Streptavidin Conjugates

Enhance detection with streptavidin and biotin conjugates, available with CF® Dyes and other labels for bright, high-affinity binding across diverse assay formats.
